the mode of a man who reaches fits of rage when his girlfriend even speaks to another male or even mentions another male. this mode often involves asking about every unfamiliar phone number on his girlfriend's cell, checking her email without her consent, following her when she goes out for the night, and will make sure that he knows where she is and who she is with at all times. thi mode is a nightmare for his girlfriend's friends as they will tell her to break up with him constantly
he's in CBM again and he won't quit calling.

Some stupid acronym made up by people that watch too much Jerry Springer, on par with "you go girl-friend" or "talk to the hand".
Uh, he was in SUCH a CBM! What-ever!

A pissed off male, usually by the woman he is romatically involved with, who is about to let the world know that he is pissed off.
